Received the Tray and clamps from Italians Flex-arm.. The Gopro tray is sturdy and the clamps are huge and amazing at same time Didn't know this italian company but by the looks of their products they are 10/10...looking forward to test in the water. Float Arms next week. So far weight on land 2590g

Ive got the specs of LS50 V2 LS50 V1 (lumens preset) 5000 3750 2500 LS50 V2 (lumens preset 5600 5040 4480 3920 3360 2800 2240 1680 1120

Lights, Camera, Action...like they say in Hollywood Angles, CRI/RA, flooding, corrosion, inaccurate lumens output, dubious quality control... and some cheap chinese dive lights will dimm faster over time. Get one good dive light once, buy a cheap light at least twice.

Ive also had a second dive light, but the LS50 V2 now has a new improved version and im scratching my head what values (lumens) the new presets 1-9 have on version V2 LS50 version 1 (5000 LUMENS ) 5600 kelvin CRI 96 100% - 5000 lumens 75% - 3800 lumens 50% 2500 lumes L50 version 2 (5600 LUMENS) 5600 kelvin CRI 96 Level 9 - 5600 lumens Level 8 - ??? Level 7 - ?? Level 6 - ?? Level 5 - ?? Level 4 - ?? Level 3 - ?? Level 2 - ?? Level 1 - 1200 Lumens Ive email divevolk to inform me what are the values (LUMENS) of Level 8, 7, 6, 5, 4, 3, 2….

Ive just bought new clamps + new underwater tray, i will use a lugagge scale in salt water when they arrive.. After the measurements i will order the floats.

New weight with luggage scale 1 x clamp INON ( fresh water 50g) 1 x LS50 with battery ( fresh water 220g) 1 x gopro13 + gopro case 1x AOI UWL-03 lens (land 650g )

I discuss the distortion lens with Osmo5 on the dji forum some time ago Im glad i went to the gopro route.. https://forum.dji.com/forum.php?mod=viewthread&tid=319140 Regarding the sensor, apparently its not block, see the video at 3m07s

Im upgrading/optimizing the system with underwater weight If anyone know what is the normal weight in salt water of : 1 x tray gopro 25x 60 x 8 Flex-arm ( fresh water 130g ) 1 x Clamp Flex-arm (fresh water 55g) 1 x dive light LS50 divevolk or Supe V3K V3 (manufacturer 295g ) 1 x gopro13 + gopro case 1x AOI UWL-03 lens (i have measured 250g underwater ) Also theres a big weight diference (up or down) when the Gear is weight individually VS when weight all-in-one ??

This Amazing documentary is a 8 years investigation about the Whale Shark migration in Açores Atlantic Waters, in the Island of Santa Maria. Director was the Award winning BAFTA Nuno SÁ. Since the documentary was broadcast in National Television RTP Play https://www.rtp.pt/play/p10414/a-ilha-dos-gigantes the Santa Maria Island was overwhelmed by request of divers all around the world to dive at Santa Maria Whale Shark spot.

I also recommend the Madeira -Funchal Best diving spots : Cordeca, Garajau, Reis Magos Visibility is +30m... Water temperature 24 degrees Affordable dives with Nitrox 35€/40€ Flights and accommodation are also affordable.

I recommend Porto Santo Water temperature 22 to 24 celsius during september and october. Best diving spots are 2 x Ship wrecks (cordeca & madeirense aprox 30m ) Affordable flights and accommodation Affordable dives with Nitrox 35€/40€ Visibility is +40m... Example https://fb.watch/v4sz1edDFV/ Ive dived in Porto Santo in September 2023 (Cipreia Dive club) 12 x dives with nitrox 430€ (pack) flights lisbon - Porto santo - lisbon 200€ Accommodation 50€/day x 6 days 300€ Return in May 2024 for the Madeira underwater open Water 2024 (video & Photography competition)

Here's video before the lens polished https://drive.google.com/file/d/1QwuHWgSGZpb2j7uYG40A_nyapMttMTVz/view?usp=share_link Heres a video 5k after being polished .. but google drive downgrade to 1080p See if you can spot the imperfection. https://drive.google.com/file/d/1bwMFZCy81MEnLQ_senhFzirH0Dqg3ug2/view?usp=share_link

Hi.. Ive put the polished lens to the test at sea and it's 99.9 perfect, better than having the scratch. Now i can use the polish lens again, and in my case the green water helps hiding the imperfection. Without certainty i believe that in Red sea, Porto Santo, Okinawa, shallow cristalin water with lots of natural light in certain conditions if you look for the artefact you can spot the imperfection, this dive i have about 20 clips and was very difficult to spot the issue. the images below are the worst ive manage to spot...

Ive used 1, 2, 3....and when couldn't feel the scratch, ive used 2, 1. I also Washed the lens with warm water when i jump from 3 to 2. Number 1 & 2 are unable to remove the deep scratch., at least in my situation. If i could do it again, i would use 1 & 2 polishing, and make an underwater test video, this way i would not touch the hard coating.

Nice video from AOI GoPro 13 + UWL-03PRO

in this print of the video AOI OLD , its possible to see the imperfections on the polished lens, but has soon enters the water, the marks gone.

I saw that guy video before i polish the lens. Ive start 1 & 2 in hope i didn't have use the number 3 Ive made 4 videos (named AOI old VS AOI new ) comparison between Old Lens and new lens in the Fish tank ... it looks promising, the water seems to fill that small gap/imperfections, but the real test will be at sea. https://drive.google.com/drive/folders/1aOsE9gbn9uVWNXV6mEsSgXFGBwrfJK72?usp=share_link here a video before being polished, once you see the scratch, you can't unseen. ps: the video is 4K 60FPS, but for some reason google drive convert it to 1080p https://drive.google.com/file/d/1XgatPbrhy64WaK2ISPDibCEVLGnHnpZ4/view?usp=share_link

I start by 1 and 2 because it was less abrasive, and i didn’t want to damage the hard coat. 1 is liquid 2 mix of solid liquid 3 more solid Polished with number 3 removed the scratch, but unfortunately was deep enough that was under the hard coating. if I had start by number 3, the number 2 and 1 they don’t restored the damage to the hard coating already done.

ok...heres the science results. This scratch is little deep, if you pass the nail you can fell it. Novus 1 - didn't do anything Novus 2 - didn't do anything Novus 3 - i start with very light pressure, 10 minutes later i start to apply more pressure but the sctrach was not going way and i could feel it if i use the nail. i was thinking, if there's a harding coating to protect the lens/dome, the amount of pressure necessary to scratch the hard coating was heavy, so to remove it i also need to put more pressure to remove it. After polishing for about 15m, i stop felling the stratch with my nail, the scratch is gone, but now there's shadow/mark (like buble mark ) now remains in the lens, i suppose ive pass the hard coating surface and reach the lens surface. I notice also, now there's more light shadow/marks (buble mark) around the old scratch area, if i continue to polishing, think more marks will come up... The Marks on the lent are VISIBLE ??? Pictures No Video YES image Screen shot of the video Yes Sink underwater test Inconclusive Its better than before Inconclusive it might be possible that the water fill that imperfections on the lens. Im going to dive this weekend and let you know.. https://drive.google.com/drive/folders/1aOsE9gbn9uVWNXV6mEsSgXFGBwrfJK72?usp=share_link

Here's the main of the reasons i didn't follow the Divevolk + Iphone for underwater filming...stabilization. But the iPhone is catching up...

AOI customer support reply the following

if you know your area RI RI - is the refractive index of the lens ?? if is the case, I couldn't find any RI value in AOI or INON lens.. No idea if this values apply to Domes source: https://www.downtownvisionnv.com/blog/the-refractive-index-explained

Ive ordered the Novus kit.... i will try to removed the light scratch and share the results..

Please Note: Theres acrylic domes and Polycarbonate domes Nauticam in their Maintenance and product care says the following : • For minor acrylic scratches, the port can be polished by micro mesh acrylic optical liquid when properly used. • Glass dome ports are heavier than acrylic dome ports, and they yield better image quality thanks to their superior optical properties. • Very minor glass scratches can be polished by mild cleaner for car windows with a dedicated towel, such as: Eco Touch car glass cleaner. Please avoid using cleaners contain harsh solvents, ammonia and alcohol which can potentially damage the glass. • For wide range of deep scratches/cuts on the dome surface, it is recommended to replace the optical element. https://nauticamindonesia.com/nauticam-product-care-maintenance-tips.pdf

The PFD specs from AOI UWL-03 says the following: Front Dome Element in Polycarbonate with Hard Coating In the video below the method to remove scratch from Polycarbonate is with heat gun blowing at 600 degrees, the lady in the video say the material will not bend because is thick, but Applying the same process in the 4mm Polycarbonate will bend but will return to its position. Not sure if i want to try this on AOI lens 🙂
